> OK, I will change CATFILE definition so that it does not hang on empty
list of input files (a sane expectation). I'm not sure how to adapt the windows
case, though. This is how the change looks for the Linux case so far:

Shouldn't cause a hang. It should generate a (uncaptured) error message and
generate an empty file:
C:\Users\spuda>type > foobar
The syntax of the command is incorrect.
C:\Users\spuda>dir foobar
Volume in drive C has no label.
Volume Serial Number is 947F-7817
Directory of C:\Users\spuda
11/25/2020 06:05 PM 0 foobar
1 File(s) 0 bytes
0 Dir(s) 943,090,741,248 bytes free
